DYEING MACHIN E.

Application filed August 14, 1922.

To all whom it may concern:

Be it known that I, THOMAS Annsor, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing Machines, of which the followin is a specification, reference being had to t 0 accom anying drawings.

This invention relates to c lindrical article holders for dyeing, bleac ing and washing machinery, and an object of the invention is to generally improve the construction of this element and more particularly to provide an improved design wherein the parts of the cylinder or article carrier are assembled with a view to avoiding parts projecting into the cylinder, such as rivet heads, bolts, flan es, etc, so that delicate fabrics and artic es may not be nagged or otherwise injured when tumbled during rotation of the cylinder.

Another object of the invention is to provide a cylinder of the character described which is polygonal in cross section, providing a series of flat sides 11 n its inner surface to ensure proper tum ling of the articles without entangling the same and Fi III is a view of the drum per se in' end elevation.

Fig. IV is a view in elevation of a. fragment of the cylinder showing a. door construction; and

Fig. V is a view in transverse section taken through the door, showing in detail an improved locking mechanism.

Fig. VI is a detail view of the locking mechanism in plan.

Fig. VII is a detail view in transverse definition of a Serial No. 581,567.

section taken on the line VII-VII of Fig. VI; and

Fig. VIII is a view of the locking mechanism in perspective.

With reference to the drawings, indicates a vat of conventional form having a door 11 for entry of articles into the cylinder or drum indicated generally at 12. The latter comprises a pair of end members, each a duplicate of the other in construction and consisting of four segmental sections 13 arranged in circumferential relation as shown in Fig. III. Each section. is formed with diverging radial sides 14, connected at their adjacent ends by means of the straight side member 15, and at their remote ends by means of the perimetrical member 16, which is bent at several laces to provide flat attachin portions 1% the latter defining the sides 0%3. regular polygon when the segmental sections are assembled. The entire perimetrical portion of each segment is preferably angular in cross section defining the inner flanges 18 and outer flanges 19. the latter being apertured at numerous places for the reception of bolts 20 to secure the segments together. The assembly hi the segments results in the uadrangular central opening within whici is fitted a journal member designated comprehensively by the numeral 21 and. comprising four substantially triangular sections 22 of duplicate constructiom-eaclr consisting of a web portion 23, a lateral base flange 24 for abutment against a flange 19 of an adjacent segment 13, converging side flanges 25 for mutual abutment and an arouate recess 26, the latter defining a central opening .for the reception of a tubular shaft or axle 27. The edges of the recesses 26 and adjacent portions of the flanges 25 are reinforced by the provision of additional metal, as indicated at 28 and 29 respectively. The thickened portions 2-9 are apertured for the reception of bolts 30'which serve to tightlybind together the parts of the journal. The structure described constitutes a drama work upon which the plates forming the sides and enclosing members are mounted. Interposed between each adjacent pair of segmental sections 13 of each end member is a perforated partition plate 31 of pernf'eted sheet metal; the ed es of i. hich are gripped between the flange edges of the plates 32 with which each segment 13 is covered. Each plate 32 is turned over along its entire perimetrical edge to provide flang es for this purpose and to overlap the entire pe ripheries of their enclosed segmental memhere 13. The outer ed es of the partition plates 31 are extended iie cry of the drum for coo eration with a door structure to be desqri ed and the inner edges of said plates extend beyond the corners of the ournal members and are gripped between the inturned edges of Jer forated sheet metal plates 33 of which our are provided in the present instance having their ends gri d between the sides of the journal members and the segmental sections 13. The meeting faces of the sections forming the journal members are recessed to receive the edges of the plates 31 and 33, said inner edges of each series contributing to form inwardly directed flanges or deflecting members 34 for a purpose to be presently noted. The plates 33 are thus arranged to form a square axial channel in the center of the drum enclosing the shaft 27, the ends of which extend beyond the drum and are anchored in opposed walls of the vat. The peripheral walls ofthe drum are formed by the provision of perforated sheet metal plates 35, the ends of which are secured to the flanges 19 of the segments 13 and are bent for,attachment to the faces 17 to form the sides of the drum imlparting a polygonal configuration thereto.

tach plate 35 is of a circumferential width to embrace only two faces 17 of each end scgmcnt exposing an opening into which articles are introduced, the door seat being provided by "the aforesaid radial extension of the partition plates 31 and the out-turned longitudinal edges 36 of the said plates 35. A number of angle bars 37 are secured to the face of the drum, one adjacent each of the said out-turned edges 36 to reinforce the drum structure and to rovidc a mounting for the door which consists of a rectangular frame 38 the, sides of which are angular in cross section and are formed with a pair of aperturcd ears cooperating with similar cars 40 formed upon the ends of the angle bars, whereby 16.;(1001 frame may be swung toward oi awa'y from the door opening to rcspoctively close or open the same, the opposed edges of the door structure abutting against and between the adjacent edges of the plate 31 and the edge 36. The door is manipulated through the medium of a bandie 41 secured to enlargements 42 formed on one side of the door frame to dispose the handle at a convenient angle for grasping. The doors are held in closed position by means of a pair of locking devices each con sisting of a bolt 43 slidably held in guiding yond the periph-' members 44 formed upon cross bars -15 con necting the longitudinal side members of the door frame. The locking bolts are urged toward locking position by means of springs 40 embracing the bolts and interposed b etwccn one of the guides 44 an a collar 47, one of which is ailixcdto each bolt. the bolts being held in openings provided in an adjacent pair of plate extensions 31 and 36. Each bolt 43 is formed with a lateral enlargement or lug 48 which is slidably held within the snugly rcceiving' opening of one of the guides 4-1 when the bolts are in locking position. When the bolts are retracted suflicient to completely withdraw the lugs 48 from their rccosscs the bolts are given a quarter turn so as to throw the lugs out of aligl'uncnt with the recesses and by engaging the faces of the guiding members 44 prevent return of the bolts to locking position. The door may now be 't'reclv opened or closed. 'hcn the door is closed and the bolts arc to be shot it is but necessary to throw'o cr the bent terminals thereof whereuponrihc springs 46 automatically resent the bolts. Each door frame is covered by means of a perforated plate 49 having outwardly turned flanges embracing the edges of the frame.

in the use of this type of machine the dyeing liquor. etc. is forced into the ubular shaft and issucs from the perforations in sprays which are directed upon the articles contained in the drum dnrinp rotation of the latter so that the articles are uniformly subjected to the action of the liquor. by this means and by submersion in the rat which is also tilled with the liquor heated by live steam issuing from a perforated pipe 50 submerged at the bottom of the vat. In the present invention the liquor discharging from the tubular shaft enters first the square axial c'hanncl of the drum and passing through the perforated plates forming the sides thereof is distributed to the several pockets into which the interior of the drum is dividcd. The distribution is enhanced by the resence of the flanges 34 which are directed radially into the axial channel and serve to deflect thc sprays from one pocket to the next during rotation of the drum. as suming the tubular shaft to be held stationary. although if desired the shaft may be fixed to the drum and the latter rotated by application of power initially to the sha ft. it will be seen that as the interior of III] the drum consists solely of plates in close contact at their edges and all having their contacting edges turned outwardly there is no opportunity for sharp projections of any kind to extend into the drum and hence the articles cannot be injured or torn irrespective of the amount of tumbling to which they are subjected. It will be apparent that this construction of drum is also applicable to good advantage in the type of machine in WhlCh the li nor is not introduced into the center at all at relies solely upon submersion of the drum in the liquor for treatment of the articles. Owing to the presence of numerous outwardly projecting fins and flanges resulting from the construction described the liquor in the vat is constantly agitated during rotation of the drum.

Having thus described my invention, I claim:

1. An article container for dyeing machines or the like, comprising perforated plates assembled to form the container and aving outwardly turned edges, va frame structure of separable parts applied to the exterior of the plates and means securing together the edges of the plates and parts of the frame to form a rigid structure.
